         2 . The chimney liner of  claim 1  further comprising a corrugation height of about 4.648 mm to about 4.826 mm and an angle of corrugation less than or equal to about 10 degrees. 
     
     
         3 . The chimney liner of  claim 1  wherein the sheet strip width is about 114 mm and the pitch is about 50 mm. 
     
     
         4 . The chimney liner of  claim 2  wherein the corrugation height is about 4.65 mm and the angle of corrugation is about 6 degrees. 
     
     
         5 . The chimney liner of  claim 3  wherein the corrugation height is about 4.65 mm and the angle of corrugation is about 6 degrees. 
     
     
         6 . The chimney liner of  claim 1  further comprising a corrugation width of about 5.8 mm. 
     
     
         7 . The chimney liner of  claim 1  further comprising a corrugation radius of about 1.27 mm to about 1.52 mm. 
     
     
         8 . The chimney liner of  claim 1  further comprising an inside diameter of about 127 mm to about 305 mm. 
     
     
         9 . A chimney liner having a profile comprising a sheet strip width of about 110 mm to about 120 mm, a pitch of about 45 mm to about 55 mm, an angle of corrugation less than or equal to about 10 degrees, a corrugation height from about 4.648 mm to about 4.826 mm, a corrugation width of about 5.8 mm, and a corrugation radius of about 1.27 mm to about 1.52 mm. 
     
     
         10 . The chimney liner of  claim 9  wherein the sheet strip width is about 114 mm and the pitch is about 50 mm. 
     
     
         11 . The chimney liner of  claim 9  wherein the corrugation height is about 4.65 mm and the angle of corrugation is about 6 degrees. 
     
     
         12 . The chimney liner of  claim 10  wherein the corrugation height is about 4.65 mm and the angle of corrugation is about 6 degrees.13. The chimney liner of  claim 10  further comprising a corrugation width of about 5.8 mm. 
     
     
         13 . The chimney liner of  claim 9  further comprising an inside diameter of about 127 mm to about 305 mm. 
     
     
         14 . A chimney liner manufacturing process comprising the steps of:
 forming corrugations in a sheet strip;   twisting and seaming the sheet strip to form a chimney liner;   wherein the corrugations form a chimney liner profile comprising a sheet strip width of about 110 mm to about 120 mm and a pitch of about 45 mm to about 55 mm.   
     
     
         15 . The process of  claim 14  wherein the sheet strip width is about 114 mm and the pitch is about 50 mm. 
     
     
         16 . The process of  claim 14  wherein the chimney liner profile further comprises a corrugation height of about 4.648 mm to about 4.826 mm and an angle of corrugation less than or equal to about 10 degrees. 
     
     
         17 . The process of  claim 15  wherein the chimney liner profile further comprises a corrugation height of about 4.648 mm to about 4.826 mm and an angle of corrugation less than or equal to about 10 degrees. 
     
     
         18 . The process of  claim 15  wherein the chimney liner profile further comprises an inside diameter of about 127 mm to about 305 mm. 
     
     
         19 . The process of  claim 14  wherein the chimney liner profile further comprises an inside diameter of about 127 mm to about 305 mm. 
     
     
         20 . The process of  claim 14  wherein the chimney liner profile further comprises an angle of corrugation less than or equal to about 10 degrees, a corrugation height from about 4.648 mm to about 4.826 mm, a corrugation width of about 5.8 mm, and a corrugation radius of about 1.27 mm to about 1.52 mm.
